Abstract: FUEL PRIMER AND ENRICHMENT   SYSTEM FOR AN INTERNAL   COMBUSTION ENGINE                 ABSTRACT OF THE DISCLOSURE       An engine comprises a combustion chamber and a fuel transfer passage having a fuel outlet port communicating with the combustion chamber. A primary fuel delivery system communicates with the combustion chamber and introduces fuel from the fuel source into the combustion chamber.  The engine further comprises a fuel pump which is adapted to be connected with a source of fuel and a fuel return line having a first end communicating with the source.  A mechanism selectively controls the communication of the fuel pump with either the fuel return line or the fuel transfer passage, so that an enriched flow of fuel can be selectively supplied to the combustion chamber prior to and after starting.

Abstract: Abstract of the Disclosure The present invention is concerned with glass-ceramic articles which are extremely resistant to impact and spon-taneous delayed breakage, are capable of being sawn with a diamond wheel to a depth of over one-third the cross section thereof without breakage, and exhibit modulus of rupture values of at least 150,000 psi.  The articles consist of a body portion and an integral surface compression layer having a depth of at least 0.005".  The body portion consists essentially, in weight percent, of about 8-13% Na2O, 7-13% K2O, 30-36% Al2O3, 35-43% SiO2, and 6-10% RO2, wherein RO2 consists of 6-10% TiO2 and 0-4% ZrO2, wherein the molar ratio Al2O3:SiO2 is >0.5 but <0.6 and the molar ratio K2O:Na2O is >1:3 but <1 and contains nepheline solid solution crystals corresponding to the formula Na8-xKxAl8Si8O32, with x varying from 0.25-4.73, as the predominant crystal phase.  The surface layer contains kalsilite as the predominant crystal phase and is produced by subjecting the base glass-ceramic article to an ion exchange reaction wherein K+ ions replace at least part of the Na+ ions in the nepheline solid solution crystals to convert those crystals to kalsilite.

Abstract: Abstract of the Disclosure Apparatus for high-efficiency drying of material includes a vacuum drying chamber (40) maintained at a low pressure by a vacuum pump (56).  Material to be dried is introduced to the drying chamber through an air lock valve (36) and is transported through the drying chamber by an auger (45).  In the preferred embodiment a second inter-connected drying chamber  (50)  includes a further auger (52), and material that has been dried is removed from the drying chamber by another air lock valve (55).  Microwave energy sources (30) apply energy to vaporize liquid from the material, and air inlets (72, 73) are provided at the processed ends to  introduce air for sweeping generally across the material to the outlet (55) to the vacuum pump. The sweep of cool air causes an aerosol mixture to form, which is removed by the vacuum pump.  Heat is reclaimed by separating liquid and vapor, with the liquid being passed through hollow shafts (60, 51) of the augers to heat the material in the drying chamber, and the vapor being sent through a heat exchanger (15) in thermal contact with a preheat zone (13) so that heat from the vapor removed from the drying chamber, including latent heat of vaporization, is transferred to the material prior to introduction to the drying chamber.

Abstract: ABSTRACT   The hot rolling of metal slabs to strip thickness and in coils having a specific weight on the order of 500 pounds per inch of width and greater comprises passing a heated metal slab through a roughing mill to form a transfer bar. The transfer bar is immediately passed between work rolls of a reversing finishing mill stand where it is coiled in a furnace downstream of the reversing finishing mill stand. Thereafter, the workpiece is passed back through the reversing finish-ing mill stand and coiled in a furnace on the upstream side thereof. The workpiece is again passed through the reversing finishing mill stand and into the remaining finishing stands where it is further re-duced and ultimately coiled in strip form. The first two passes through the reversing finishing mill stand are carried out at speeds in excess of the third pass and unrelated to the speed cone of the remainder of -the continuous finishing stands. The third pass through the reversing finishing mill stand is carried out at a rolling speed consonant with the speed cone on the subsequent passes through the continuous finishing stands .

Abstract: ABSTRACT OF THE DISCLOSURE           A sorting machine is provided for attachment to a copying machine  to receive successive sheets from an outlet from the copying machine.  The sorting machine has plural trays mounted to move progressively past the sheet outlet in opposite directions, the trays being relatively close together when positioned at either side of the outlet, but adjacent trays being widely spaced to accommodate the incoming sheets from the outlet.  The trays are fed past and spaced at the outlet by driven members at opposite sides of the tray which engage and shift stacked trays in succession.  The driver members are notched discs funtioning as a linear Geneva movement.  The remote ends of the trays are freely supported one on the other for relative longitudinal and pivotal movement.  In certain forms, the remote tray ends are mounted one on the other by end pieces which have wedge surfaces causing the remote ends to be spaced apart respon-sive to longitudinal movement of the trays.

Abstract: Abstract of the Disclosure In a control system for a gas heated water or air heater, the use of the supplied fuel gas is to be improved by automatically determining and supplying the amount of air which is required for obtaining complete combustion.  A gas control valve feeds a burner with the required amount of gas dependent on the demand of heat.  A sensor responding to the content of oxygen or carbon dioxide within the flue gases is located in the stack and the output signal of this sensor is compared with a set point within an electric controller.          In case of a control deviation, the output signal of the controller controls an adjustable source of air under pressure formed by a fan with subsequent air control valve in such a manner that the required amount of air for reaching optimum combustion is supplied.
